HEAD acoustics Launches VoCAS Speech Recognition Evaluation Software

German company HEAD acoustics launched VoCAS (Voice Control Analysis System), an efficient software analysis solution for evaluating speech recognition systems. From voice control in vehicles to the use of speech commands for smartphones, tablets or telephone hotlines, VoCAS allows quick and objective quality evaluation, under realistic and repeatable test conditions, of Automatic Speech Recognition (ASR) systems, found in an increasing number of applications today.

Boston audio and electroacoustic test and measurement specialist, Listen is promoting another edition of its popular 2-day SoundCheck training class on May 17-18th in Elgin, IL (just outside Chicago). This will be a not-to-miss opportunity until the company holds its California SoundCheck and Electroacoustics Training, later in October, in Santa Clara, CA.

Audio Precision announced the introduction of their Speech Transmission Index (STI) plug-in for APx500 audio test software. Created for engineers developing public safety (police, fire, emergency) communications and public address systems, as well as flight recorder devices, the APx STI plug-in provides measurement capabilities conforming to international standard IEC 60268-16 (2011).

Audio Precision announced the release of their newest driver for National Instrument’s LabVIEW software, which enables easy access to APx515 as a data acquisition platform. Additionally, the driver enables control of the APx515 completely independent of the APx500 control software.

NTi Audio, headquartered in Schaan, Liechtenstein, NTi Audio attended this year’s meeting of the Swiss Acoustical Society (SGA), held under the theme “Practical Sound Measurements”. NTi presented its XL2 Audio and Acoustic Analyzer and provided practical demos of environmental noise, speech intelligibility, RT60 and sound insulation measurements.

NTi Audio provides a tool to derive octave and one-third octave band results from FFT measurement results using the FX100 Audio analyzer, as required by audio applications where standards require octave or one-third octave band measurements.

As the Speech Transmission Index for Public Address Systems (STIPA) now enters its second decade, NTi Audio reflects on the early years and how the process evolved through active interaction with international standards committees. Meanwhile, NTi Audio has released the Wave File Converter, a free PC software that allows creating custom files for playback through NTi Audio signal generators.
